Print widget scale bar problem

I published a printing service so I could use my templates. The templates include a scale bar. For some reason the scale bar doesn't match the scale of the map when it prints. It adjusts when I check the 'Use this Scale' option as an end user, but it isn't correct either way.

Attaching some pictures to show how this string of 50' lots doesn't scale properly.

I am stumped. Any insight as to why this would happen would be helpful.

Turns out this is a known bug.

Documented here.

Can this known limitation of the Flex Viewer be added to the help documentation so that future users won't waste hours trying to find this simple answer?

I found a solution to this bug on another site. The scale bar was not correct when printing from an application in Web Mercator. You need to adapt the Print.js file of the print widget and change the following line:

this.printparams.outSpatialReference = this.map.spatialReference;

into something like:

this.printparams.outSpatialReference = new SpatialReference(32631);

32631 has to be changed to a Spatial Reference WKID of your region. My MXD templates used by the print service are having the same reference system.

And of course, you have to

define(["esri/SpatialReference" ...], function (spatialReference...

in the beginning of the Print.js file (the order of elements in the define-part has to be the same as in the function-part)

No idea why ESRI commented out the following line in the print.js code.

//fix issue #7141
// this.printparams.outSpatialReference = this.map.spatialReference;
